Changes to templates, temporary view

Made some changes to the templates (and added a little CSS). Added a static
route for css (/css/). The map template actually opens the right image now. The
map page actually shows the right image map now. Pokemon are sorted in the table
properly (really happy about this). Moved the route images around.

Unfortunately I might have to attain these images myself... which probably
entails having to play one fo these games on an emulator and screenshotting a
lot. Tried to contact the guy that ripped the images initially, but I haven't
heard from him.
